How to replace the Iceriver control board?

Iceriver control board, CPU chip model Xilinx XC7Z010, with 4 4pin fan interfaces, suitable for Iceriver KS3M, KS3L, KS3, KS2, KS1 and other KAS miners. The control board is mainly used to collect and process the hash board operation data.

If the Iceriver miner has a low hash rate or 0 hash rate, abnormal fan speed, indicator light is off or red, and the background log shows that the IP cannot be found, fails to enter the miner's backend, or misses chain etc., This may be caused by an abnormal control board.When the problem of the control board cannot be solved by upgrading the firmware, we should immediately replace the faulty board with a new spare Iceriver control board to quickly restore the normal operation of the miner.

Taking the Iceriver KS3M miner as an example, the specific steps to replace the miner control board are as follows:

1. Turn off the power, remove the protective cover of the control board, take out the conductive copper sheet, and unplug all cables;

2. Unscrew the fixing screws of the control board, push the problematic control board forward to the bottom and remove it;

3. After checking that the new Iceriver backup control board is in good condition, install it in its original position and secure it;

4. Connect all cables on the control board and make sure the connections are tight;

5. Install conductive copper sheets, then put the protection cover on;

6. Power on the miner and insert the TF card with the corresponding flashing file into the card slot of the control board. If "PASS" appears in the displayed result, the firmware refresh is completed. Turn off the power and pull out the TF card;

7. Restart the miner to check its running status.

In an increasingly competitive mining industry, keeping miners running at their best is crucial. ZEUS MINING recommends keeping a certain inventory of Iceriver replacement control boards so that miners can replace them promptly when the control board is damaged and avoid unnecessary downtime losses.
